IBS gas and bloating relief

Bloating is the sensation of fullness or visible abdominal swelling. Gas can build when swallowed air mixes with fermentation of carbohydrates in the bowel. IBS can make normal stretching feel more uncomfortable, so the amount of gas does not always match the intensity of the sensation. Food intolerance, lactose intolerance, coeliac disease, infection and other digestive conditions can look similar. A new pattern, especially one that persists, deserves a broader assessment rather than being automatically attributed to IBS.

Eat slowly, chew thoroughly, and consider smaller regular meals. Reduce fizzy drinks and notice whether chewing gum, straws, or particular carbohydrates increase swallowed air or fermentation. Gentle walking can encourage bowel movement. Keep a diary of portions, ingredients, constipation, diarrhoea and discomfort. Do not start a highly restrictive diet without guidance; a dietitian can help test likely triggers while protecting nutrition. Ask a pharmacist or clinician before using a medicine for gas, particularly if you take other medicines or are pregnant.

Seek medical advice for bloating that is new, steadily worsening, persistent, or associated with unexplained weight loss, blood in the stool, repeated vomiting, fever, or a persistent change in bowel habit. Get urgent help for severe or sudden abdominal pain, a swollen abdomen with inability to pass stool or gas, fainting, or marked weakness. These features need assessment even when previous symptoms were labelled IBS.

Could constipation, intolerance, coeliac disease or another condition be contributing? Which foods should I test first? Would nutrition counselling help? Is a medicine suitable for my symptoms, and what warning signs should I watch for?
